Description

The length of the shell attains 13.5 mm, its diameter 4.5 mm.

The elongate turriform shell is white in the subsutural and peripheral region, with the remainder reddish brown. The basal part of the body whorl shows rows of white dots. The shell contains 6-7 whorls, which are concave on top and convex below. The axial ribs are initially arcuate and in later whorls opisthocline, numbering 12 on the penultimate whorl. The dense, spiral threads are very small. The aperture is oblong-ovate. The wide anal sinus has an U-shaped form. The columella is almost straight. The sharp outer lip is thickened towards the suture.[3]

Distribution

This marine species is endemic to endemic to Lifou, Loyalty Islands.

gollark: Probably chemical weapons, if I couldn't just use nuclear ones.
gollark: If I was a vast global conspiracy bent on killing a significant fraction of the population for poorly specified reasons I assume I could do better.
gollark: Also aging.
gollark: Well, see, oil companies cause global warming, which causes bees.
gollark: Very impressive.
